Description
- The present application claims priority from U.S. Provisional Application Ser. No. 61/239,827, entitled Equipment Racks Utilizing Rail Engaging Retaining Brackets That Limit Chassis Movement, filed Sep. 4, 2009 and incorporated herein by reference in its entirety.
- The inventive subject matter relates to equipment racks, rack mount hardware, and methods of mounting equipment therein.
- Racks with provision to mount electronic chassis are commonly used in telecommunications and computer networking applications. A typical data center, for example, may include multiple racks in which equipment chassis, e.g., servers, storage units, power supplies and the like, are inserted and mounted. Such racks commonly include rails that are mounted in horizontally opposed pairs in the rack and provide shelves or ledges that support an inserted equipment chassis. The equipment chassis may be secured in the rack by fastening a front flange thereof to a mating surface of the rack or rails.
- Conventional rack mounting arrangements may not provide adequate constraint of movement of the equipment chassis mounted therein. Therefore, significant movement of the equipment chassis may occur when, for example, the rack is being transported or subjected to vibration testing. Conventional techniques for constraining such movement may involve the use of specialized retaining hardware that affixes the rear end of an equipment chassis using loose hardware components that often must be removed when the rack is prepared for use, so that the chassis is freed to slide on the rack rails.
- Some embodiments of the inventive subject matter provide an apparatus including an equipment chassis configured to house electronic circuitry and to be inserted in an equipment rack between an opposed pair of rails. The equipment chassis includes a bottom face configured to rest on shelf members of the rails. The apparatus further includes a retaining bracket disposed at a side face of the equipment chassis facing one of the rails and oriented substantially perpendicular to the bottom face of the equipment chassis. The retaining bracket is configured to engage a horizontal groove in the one of the rails when the equipment chassis is inserted horizontally into the equipment rack between the rails. The retaining bracket may be configured to engage the one of the rails to limit vertical movement of the equipment chassis. Such retaining brackets may be provided on opposites side faces of the equipment chassis such that they engage grooves of respective ones of the opposed rails.
- In some embodiments, the retaining bracket is fastened to the side face of the equipment chassis. In further embodiments, the retaining bracket may be integrated in a housing of the equipment chassis.
- In some embodiments, the retaining bracket includes a planar member conforming to the side face of the equipment chassis and a flange extending perpendicularly from the planar member and configured to engage the groove. An upper surface of the flange may face an upper interior wall of the groove when the equipment chassis is inserted horizontally into the equipment rack between the rails. An end of the flange may be bent such that the end is deflected away from the upper interior wall of the groove when the flange is deployed in the groove.
- In further embodiments, the retaining bracket may be disposed proximate a rear of the equipment chassis such that it is positioned proximate a first end of the one of the rails when a front mounting flange of the equipment chassis is attached to a mounting flange of the one of the rails proximate a second end thereof. The one of the rails may include a flange positioned in the groove proximate the first end of the one of the rails and configured to engage an upper surface of the flange of the retaining bracket to further limit movement thereof in the groove when the equipment chassis is fully inserted into the equipment rack.
- Further embodiments of the inventive subject matter provide an apparatus for constraining movement of an equipment chassis mounted in an equipment rack between an opposed pair of rails, the equipment chassis including a bottom face configured to rest on shelf members of the rails. The apparatus includes a retaining bracket configured to be fastened at a side face of the equipment chassis facing one of the rails and oriented substantially perpendicular to the bottom face of the equipment chassis. The retaining bracket is configured to engage a horizontal groove in the one of the rails when the equipment chassis is inserted horizontally into the equipment rack between the rails. The retaining bracket may be configured to limit vertical movement of the equipment chassis.
- In some embodiments, retaining bracket includes a planar mounting member configured to conform to the side face of the equipment chassis and to be fastened thereto and a flange extending perpendicularly from the mounting member and configured to engage the groove. An upper surface of the flange may face an upper interior wall of the groove when the equipment chassis is inserted horizontally into the equipment rack between the rails. An end of the flange may be bent such that the end is deflected away from the upper interior wall of the groove when the flange is deployed in the groove.
- In further embodiments, an apparatus includes an equipment rack including an opposed pair of rails mounted horizontally therein and an equipment chassis housing electronic circuitry and positioned between the opposed pair of rails. The equipment chassis includes a bottom face resting on shelf members of the rails. The apparatus further includes a retaining bracket disposed at a side face of the equipment chassis facing one of the rails and oriented substantially perpendicular to the bottom face of the equipment chassis, the retaining bracket engaging a horizontal groove in the one of the rails to limit vertical movement of the equipment chassis. The retaining bracket may be fastened to the side face of the equipment chassis or integrated in a housing thereof.
- The retaining bracket may include a planar member conforming to the side face of the equipment chassis and a flange extending perpendicularly from the planar member and configured to engage the groove. An upper surface of the flange may face an upper interior wall of the groove. An end of the flange may be bent such that the end is deflected away from the upper interior wall of the groove. The retaining bracket may be disposed proximate a rear of the equipment chassis such that it is positioned proximate a first end of the one of the rails and a front mounting flange of the equipment chassis may be configured to be attached to a mounting flange of the one of the rails proximate a second end thereof.

FIG. 1 illustrates arack 100 having one ormore equipment chassis 110 that house electronic circuitry mounted therein. As shown, anequipment chassis 110 is supported byrails 120 that are mounted tovertical posts 102 of theequipment rack 100. -
FIG. 2 illustrates theequipment chassis 110 in greater detail, with therails 120 removed for purposes of illustration. Retainingbrackets 130 are affixed to side faces 112 of theequipment chassis 110. As shown inFIG. 3 , the retainingbracket 130 includes aflange 132 extending perpendicularly from a mountingmember 135. Theflange 132 is bent at ends 133. The mountingmember 135 hasholes 134 therein configured to accept screws or bolts for affixing the retainingbracket 130 to theequipment chassis 110. Although the retainingbracket 130 is shown as a discrete piece, it will be appreciated that, in some embodiments, thebracket 130 may formed integrally with theequipment chassis 110, e.g., theflange 132 and other features of thebracket 130 may be incorporated in a housing of thechassis 110. It will be appreciated that asingle retaining bracket 130 may be used, or retainingbrackets 130 may be used on respective opposite side surfaces 112 of theequipment chassis 110 to engagerails 120 on each side. -
FIG. 4 illustrates features of arail 120. Therail 120 may include front andrear portions rail 120. The front andrear rail portions rear flanges rail 120 to thevertical posts 102 of therack 100 using, for example, aclamping mechanism 120 or other means for attachment, such as screws or bolts. Thefront flange 123 further includesholes 121 configured to accept screws or bolts for attaching a mating front flange of theequipment chassis 110 when thechassis 110 is inserted in therack 110 along therail 120. Thefront rail portion 122 also includes ashelf member 126 that is configured to support a bottom face of anequipment chassis 110 when thechassis 110 is inserted in therack 110 along therail 120. - As further illustrated in
FIGS. 4 and 5 , thefront portion 122 of therail 120 has agroove 127 formed therein. Thegroove 127 is configured to engage the retainingbracket 130 illustrated inFIGS. 2 and 3 . In the illustrated embodiments, thegroove 127 extends from a point proximate thefront flange 123 to a point proximate an end of thefront rail portion 122, such that anequipment chassis 110 having thebracket 130 affixed to a side face thereof may slide along therail 120 with theflange 132 of thebracket 130 engaging thegroove 127. Thebends 133 in theflange 132 deflect ends of theflange 132 away from an upper inner sidewall of thegroove 120, which may reduce binding as thebracket 130 moves along thegroove 127 and may ease alignment of thebracket 130 with thegroove 127 when inserting thechassis 110. As further shown, thefront portion 122 of therail 120 may further includeflanges 128 that are configured to engage theflange 132 of thebracket 130 to provide enhanced constraint on vertical movement of anequipment chassis 110 with respect to theshelf member 126 of therail 120 when fully inserted along therail 120. As shown, theflanges 128 may be formed by cutting and bending out sheet metal that forms thefront rail portion 122, but it will be appreciated that theflanges 128 may take other forms, such as mating brackets configured to be affixed to therail 120. As shown,multiple flanges 128 may be provided at different positions along therail 120 to accommodateequipment chassis 110 of different depths. - There are several potential advantages offered by embodiments of the present inventive subject matter. Conventional rack mounting arrangements that do not include a rail retaining bracket as shown herein may not provide adequate constraint of movement of the rear portion of the equipment chassis when mounted in the rack. Thus, significant movement of the equipment chassis may occur in such arrangements when, for example, the rack is being transported or subjected to vibration testing. Conventional techniques for constraining such movement may involve the use of specialized retaining hardware that affix to the rear end of an equipment chassis using loose hardware components that often must be removed when the rack is prepared for use so as to allow the chassis to slide along the rails of the equipment rack. In contrast, retaining brackets as shown herein may be left in place after installation, as they can provide a vertical movement constraint without affixing the equipment chassis to a rack or rail. The retaining brackets may also be symmetrical, allowing the same part to be used for right and left sides of the chassis. The mounting of the brackets may also be adjustable to accommodate variations in mounting tolerances.
- The foregoing is illustrative of the inventive subject matter and is not to be construed as limiting thereof. Although a few exemplary embodiments of this inventive subject matter have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this inventive subject matter. Accordingly, all such modifications are intended to be included within the scope of this inventive subject matter. Therefore, it is to be understood that the foregoing is illustrative of the inventive subject matter and is not to be construed as limited to the specific embodiments disclosed, and that modifications to the disclosed embodiments, as well as other embodiments, are intended to be included within the scope of the inventive subject matter.
